ECX的音标

But GCC won't know this unless we inform it, which is exactly what we do by including% eax and% ecx in the clobbered register set.

但GCC在我们通知它以前是不知道这些的，我们是通过将%eax和%ecx包括在修饰寄存器集中来通知GCC的。

Unless this is done, GCC assumes that% eax and% ecx are free, and it may decide to use them for storing other data.

在完成这一步之前，GCC假设%eax和%ecx是自由的，它可能决定将它们用作存储其它的数据。

The count value is put into% ecx as it is needed by rep prefix.

因为rep前缀需要count值，所以将它放入%ecx中。
